I behave the same way here as I do everywhere else for the most part with the same general personal rules:
Don't be a dick. These are still humans.
Don't say anything about anyone you wouldn't repeat or answer to if confronted.
I can do and say whatever the fuck I want and so can everyone else. Each holds the power to choose to not respond nor care.
Block and mute work, use them. Nobody is forcing you to participate.
Pick your battles, associations, responses wisely.
Everyone will form an opinion of me regardless. That opinion is none of my business. 🤷🏾idc what anyone thinks about me ultimately.
